If you love knitting, it is safe to say that no second invitation is required to get out the needles and some colourful yarn.
Even so, there are times when big causes and special occasions can provide a special incentive. For some, that might be the imminent arrival of a baby in the family, while others might get involved in a charity project.
This month, however, is offering an event for absolutely everyone who likes to knit, no matter who they are or where they live. World Wide Knit In Public Day is the biggest knitter-run event on the planet and everyone can take part through an event put together by local volunteers.
It takes place each year from the second Saturday to the third Sunday of June, so this year it will be taking place from June 14th-22nd.
Events taking place around the world are enormously varied. For example, in Belgium the Urban Stitchers Workshop in Leuven will be involved in a bee-friendly project, in which participants will stitch together little woolly bees or flowers.
They will even be at it on the other side of the world, with the Midwinter Knitters of Arrowtown Otago holding a day called The Stitching Post on June 21st - which is, after all, midwinter's day over there - in which lunch and tea will be provided while knitters can learn more about how to improve their craft.
While such events are occurring elsewhere in the world, there will be plenty in Britain - including one near you.
For instance, anyone who ever fancied knitting a model plane can pop along to Birmingham Central Library to find out how on June 14th.
Beginners in Berkshire can start even sooner by popping down to the Corn Exchange in Newbury on June 12th for a free stitch and chat day, with items produced at the event going on display in the town's New Greenham Arts gallery.
They will be at it in Scotland too, with a Knit For The Fun of It day at Strathpeffer Station on June 21st.
So with so much knitting fun to be had, now may be a good time to stock up on some yarn ahead of the event.
